I thought it was awesome. I think it’s the best introduction to Node and Express that I’ve found. It’s got clear explanations for how and why Express works the does, and it does it in such a compact format. Highly recommended.

So far I think Express in Action is by far the best book on the subject I have attempted. I think that’s because it assumes JavaScript proficiency at the outset, so it can focus on more complex topics like an entire chapter on testing without covering “what’s a function?” and so on.
